RTI stands for Reflectance Trasformation Imaging.

Infrared RTI

Last night i took the artwork from my wall and did my first infrared RTI. I would say it is even more exiting than normal RTI as you will see things you are not able to see with naked eye. Artwork I was taking photos of was not maybe the best to show the potential of IR RTI but I hope to try it it again with bigger light-source (I used converted Maglite Mini) and more challenging art-piece. Click on image to switch in between normal photo and IR RTI with specular enhancement filter. Continue reading →

Recent RTI work at the National Archives, Kew

Myself and Peter Wheeler spent a week working at the National Archives recording a number of different items using RTI. The work was a continuation of the DEDEFI project that Hembo Pagi completed in 2011. The majority of the work was from the 19th century Records of the Patent Office books specifically looking at Patents, Designs and Trade Marks Office and predecessor. In total we recorded 56 RTIs over the space of the week and we had time to also record a few Medieval seals for Adrian Ailes. Continue reading →

Multispectral world

Last weekend I spend some time with ACRG multispectral camera (converted Nikon D700). I got Hoya R72 infrared filter and walked on the fields of Western Estonia. I am very happy with results (see below). When it became dark outside I took the soldering iron and made two-led IR torch. This will be used for RTI testing later this week. One thing I found out already, you need quite long exposure time for a sharp image or/and much brighter light source. Continue reading →

Microscopic RTI

To fully appreciate the application of RTI in conservation practice, one should take into consideration conservation needs for limited human-object interaction, high quality and affordable visual analysis, microscopic levels of detail and advanced documentation. There is no doubt that methodological developments are necessary in order to meet those needs. One of the most obvious of these, even from the earlier stages of our research, was the microscopic level of detail required for conservation. Continue reading →

RTI workshops in Somerset

AHRC RTISAD project legacy – update one year on

It has now been a year since the AHRC RTISAD project officially ended. We have been busy developing our RTI and related imaging facilities here at Southampton, training new staff and students, continuing our outreach activities and undertaking research and consultancy projects. As we proposed in the application we have put in place a funding system that allows us to charge where appropriate at cost for use of our imaging facilities and staff. Continue reading →

GigaPan imaging

The Archaeological Computing Research Group have begun to take advantage of GigaPan imaging within our analysis of archaeological datasets. GigaPan imaging offers the first solution for shooting, viewing and exploring high-resolution panoramic images in a single system, in other words, we are able to incorporate a number of images within one single crisp and vivid panorama. GigaPan imaging can be used in relation with a number of different datasets. Continue reading →
